HARROW.

Application filed April 19, 1923. Seriall No. 633,251.

This invention relates to farming implements and the primary object of the present invention is to provide novel means for mounting a disk harrow on wheeled carrier and means for raising and lowering the harrow on the carrier, whereby the hai-row can be readily moved from one field to another or along a roadway without hurting the harrow disks.

A further object of, the invention is to provide an improved farm implementembodying a frame, gangs of ground working disks carried by the frame, means for adjusting the angle of the gangs of ground working disks in relation to the frame, and means for raising and lowering the disk gangs in relation to the frame and to the ground.

A still further object of the invention is to provide an improved farm implement of the above character, which will be durable and eflicient in use, one that wili be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

lith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings :4

Figure 1 is a section through the improved disk harrow taken on the line A-A of Figure 2.

Figure 2 is a section taken through the improved harrow on the line B--B of Figure 1.

Figure is a section taken at right angles to Figure 2 onthe line CC of Figure 2.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved farm implement constructed in accordance with this invention, which includes a pair of disk harrow gangs and l@ and the main frame D therefor.

The disk h arrow gangs B and C are of the ordinary or any preferred construction and each embodies a shaft 5 on which are mounted at predetermined -equidistantly spaced points the harrow disks 6,

The main frame D comprises a centrally disposed .forwardly extending beam 10, the forward end of which carries a truck 1l. to which can be attached any preferred type of draft appliance la. The rear' e d et' the haan-i in" has rigidly ur.;- red :a the transversely extending cross bar 13 which is of substantially an inverted U-shape when viewed in front elevation. This transversely extending cross bar 13 has its terminals bent downwardly and outwardly as at lil, and these bent down terminals terminate in rear-- wardly extending attaching feet 15 which are pivotally connected by means of pivot bolts or the like 16 to bearings 17 which rotatably receive the axles or shafts 5 of the disk gangs B and C. Bearings 19 and 2O are carried by each end of each shaft 5 of the gang disks B and C for supporting the said gangs, and these bearings are carried by brackets 21 which are secured tov transversely extending disk gang auxiliary supporting frames or members 22. These disk gang auxiliary' supporting members or frames 22 embody spaced parallel bars 23 and connecting cross bars 24. ylhe outer terminals of the harrow disk gang auxiliary supporting frames or members 22 carry outwardly extending supporting arms 25 to which are secured sleeves or bearings 26. These sleeves or bearings 26 slidably support posts 27, the lower terminals of which carry outwardly extending axles 28 upon which are rotatably n'iounted the ground engaging wheels 29 which cooperate with the truck 11 for supporting the said harrow disk gangs. The extreme outer ends of these arms 25 carry upstanding supporting brackets 30. These brackets 30 have suitable bolts or the like 31 carried by the upper end thereof, which are adapted to be engaged by the outer ends oi' the op rating levers 32. rlhe operating levers 32 are pivotally secured intermediate their ends at 33 to suitable quadrants 3e which are rigidly connected with the posts 27 in any preferred way. It is thus obvious that by raising and lowering the outer ends of the levers 32 that the frame D can be raised and lowered on the posts 27. These levers preferably carry suitable dogs or the like for engaging the quadrants to permitof the holding` of the frame D in an adjusted position. rlhe movement of the levers 32 of course raises and lowers the outer ends of the frame members 22 and in order to permit the raising and lowering of the inner ends thereof, a second operating lever is provided. This operating lever 35 is pivotally secured as at 36 to a rearwardly and upwardly extending beam 37 'which is secured in any preferred way to the forward en" of 'aa-nu 'tft "ilu @reina rear end et lll@ lll)

By operating` this lever the bell crank ll-Ok erin be rocked which Will of course riiise or lower the inner ends oi'i' the 'fr-(unes or ineinbers 2Q.
